trigonometricdemo.java

初期JAVA学习非常有用的资料。帮助深入了解API。特别是Applet。

public class TrigonometricDemo {
    public static void main(String[] args) {
        double degrees = 45.0;
        double radians = Math.toDegrees(degrees);

        System.out.println("The value of pi is " + Math.PI);
        System.out.println("The sine of " + degrees + " is " + Math.sin(radians));
        System.out.println("The cosine of " + degrees + " is " + Math.cos(radians));
        System.out.println("The tangent of " + degrees + " is " + Math.tan(radians));
        System.out.println("The arc sine of " + degrees + " is " + Math.asin(radians));
        System.out.println("The arc cosine of " + degrees + " is " + Math.acos(radians));
        System.out.println("The arc tangent of " + degrees + " is " + Math.atan(radians));
    }
}
